Hindbrain expression patterns of hoxb1b-regulated genes. 18 hoxb1b-regulated genes identified as expressed in the hindbrain were assayed by themselves (1^st and 3^rd column) or as double in situ hybridization together with krox20 (2^nd and 4^th column; krox20 is expressed in r3 and r5 and is detected in red). Based on the double in situ hybridizations, it was determined which rhombomeres express each of the novel genes and this is indicated in each panel in columns 1 and 3. All embryos are at 14hpf and are shown as whole mounts in dorsal view with anterior to the top. In situ panels in columns 1 and 3 are duplicated from Fig. 2 for ease of comparison.
